GARBAGE-BURNING FURNACE.

application filed December 2, 1915.

a. Furnace oi particular design involving, certain fundamental elements in the nature oil a fuel grate and coihierating hatlle wall. together with an (XUUSIOII oi the 'rate be yond said wall; an auxiliary incineration grate and retaining "all; and the dispositlon oi a smoke stack outside of the furnace communicating with the furnace in such a manner as to cause. a circulating draft whereby the incinerating operation will be more efiieicntly and expeditiously carried out.

A further object of the invention-is to provide a furnace of the character. described that will be substantial and ellicient. and one in which the several parts will cooperate in 2 ha X'IIHPHlUUS i'naniler.

With the above and other objects in view the invention has relation to certain novel iiimtures of construction and operation, an example oi which is deserilwd in the following specification and illustrated in the accompanying drawings, wherein:

the top of the furnace and closed by a. cover 9, By removing the cover garbage and other waste matter may be dumped into the furnace. The rear wall 3 is curved downward and, forward from a line substantially coincident with the base of the arch and merges into a dished portion in the upper surt'aee of the base. This curved portion is under the opening 8 so that the garbage will have a tendency to work forward as it is fed into the furnace. A

At the front end of the base an ash grate 11 is disposed over a pit 12. Doors 13 give access to the grate and pit. incinerated waste matter on top of the pile in the furnaee hamber may be raked onto the grate at intervals so that the ashes will fall into the pit below, while the unconsu ned matter will rest upon the grate. This latter matter may be consumed readily by opening the lower door 13.

Adjacent the side wall 4 a fuel grate 1% is arranged and extends rearward from a fire opening 15 in the front Wall. An extension grate 16 in the form of a continuation of the grate 1% is also provided. The grates are over a pit 1T whiclris closed at its frontend by a door 18: while the fire openin j is also closed by a door 18. (in the side oi the grate 1+ opposite from the wall l a batlle wall 19 extends rearward from the front wall 2 and from the base 1 to the arch (3. Between the walls l and 19a fuel fire box is formed over the grate 14. the greater portion of the grate l6 projeetingbeyond the rear end of the baflle wall. Along the opposite side of the furnace contiguous to the wall 5 auxiliary grates 20 are arranged and se iarated from the dished portion 10 by a low retaining wall Access is bad to these latter grates through. an opening in the front wall and a pit is provided under said grates. Doors Elelose the open ing' 29. and the front end of the pit. The wall 21 prevents liquids running over onto the grates from the portion 10.

Outside of the furnace a smoke staelt or fine 25 is constructed eitherag'ainst or adjaeent the wall 5. The furnaee has eonnnunication with the stack through a horizontal. duct 26 disposed at the spring of the arch 6. whereby it is elevated above all the. grates and Creates an ellicient draft. Access to the slack may he had through a clean-out door 37 disposed below the duct.

"In operating the furnace a fire is first built upon the grate 14, fuel being intro duced through the opening 15 A considerable draft will be produced by the stack 25 which causes the heat units to circulate in the furnace chamber in the general direction of the duct 26, the rear end of the bafiie wall 19 being rounded to promotecircula tion. The furnace is heated to the proper temperature, when the cover 9 is removed and garbage and other waste matter intro duced through the opening 8. Owingto the forward curvature of the rear wall 3 the matter falling thereon has a .tendency to work forward into the dished portion 10. The smoke and gases are drawn across the furnace and upward toward the draft opening or duct 26. Sufficient heat is had in the furnace to consume all gases andsmoke and to rapidly incinerate thegarbage and waste matter. All oils and liquids will be held in the portion 10 until evaporated; while the incinerated matter is raked onto the grate 11 1 at intervals. A certain portion of the garbage may be used for fuel and for this purpose the extension grate 16 is provided so that a portion provided with an opening whereby garbage may be introduced into the chamber; a fire box within the chamber in proximity to one wall thereof; a baflie wall extending upward from the base of the chamber adjacent the fire box and also extending rearward from the front wall but terminating short of the back wall of the chamber; a grate in the firebox having an extension projecting beyond the rear end of the baffle, wall; and a stack disposed adjacent the wall opposite that adjacent the fire box, said stack having communication with the chamber.

2. In a garbage burning furnace; a combustion'chamber having an .arched top provided with an opening for admitting garbage; a base at the bottom of the chamber; a fuel grate at one side of the chamber; a vertical baflie wall extending rearward from the front wall of the chamber and cooperating with the grate and/its adjacent wall to provide a fuel fire box; an extension fuel grate projecting beyond the battle Wall; an ash grate at the central front portion of the base; auxiliary garbage grates at the side of the chamber opposite to the fuel grates; a retaining wall contiguous to the auxiliary of each deposit of garbage may be raked grates; and an exterior stack having com- .thereonto if desired. The grates 20 may be used for burning the garbage which may be raked on the same and by opening the lower door 24 suflicient oxygen is admitted to promote the combustion of the matter on the grates 20.

It is obvious that most any condition encountered in the incineration of garbage and other waste matter may be handled to the best advantage in this furnace and further that it may be operated at a minimum expense owing to its economic fuel arrangements.

W hat I claim, 1s:

1. In a garbage .burnm'g furnace; a com- "bustion chamber havin a base and front side and back walls rising from the base together with an arch connecting the walls and munication with the chamber through a duct over the auxiliary grates.

3. In a garbage burning furnace; a combustion chamber having an arched roof provided with an. opening for admitting garbage; a base at the bottom of the chamber having a dished portion into which the rear wall. of the chamber is merged; a fuel grate at one side of the chamber, said chamber having a draft duct at its opposite side; a vertical bafi'le wall adjacent the fuel grate; an auxiliary garbage'grateon the duct side of the chamber; a retaining wall separating the auxiliary grate from the dished portion of the base; and a stack communication with which is had through the duct.

In testimony whereof I allix my signature.
